Add a way to invoke dive for introspection

[tfoote]

Dive can be invoked easily with just a docker command, we could relatively easily provide introspection into the results of builds with this in rocker.

docker run --rm -it -v /var/run/docker.sock:/var/run/docker.sock wagoodman/dive:latest <IMAGE_ID>

Hi @tfoote ,

I've completed the implementation for the Dive invocation feature! I added an optional --dive flag that allows users to introspect Docker images using Dive after building. The flag seamlessly integrates with the Rocker workflow.

I'll have submitted a pull request. I'm excited to contribute and help the community grow! Let me know if there's anything else you'd like me to address.

Best regards,
Ritik Kumar
